Secrets From the Set of Eclipse!

While you might not be able to visit the Vancouver set of Eclipse while Robert Pattinson, Kristen Stewart and Taylor Lautner are hard at work, don’t worry — OK!’s got you covered with all the best behind-the-scenes secrets from the set!

1. Kristen kisses Rob — then laughs!
Not to ruin the illusion, but after Rob and Kristen, who play Edward and Bella, shoot their big kissing scenes, they break out laughing — then go chain-smoke. “Kristen’s the first to laugh, cracking up like a schoolgirl,” an on-set source tells OK!. On the other hand, the passionate Bella-Jacob kissing scene in Eclipse is serious business. Author Stephenie Meyer insists it be faithful to the book. During that one kissing scene, “Taylor Lautner was way into it,” the insider says. “He didn’t break character after director David Slade yelled, ‘Cut!’ ”

2. Competition in the weight room
Cast members spend hours in the gym (the vamps need upper-body strength for flight scenes; the wolf pack have to show off their abs). Chaske Spencer, who plays wolf-pack leader Sam Uley, charts Rob’s reps. “Chaske keeps track of how much weight Rob lifts,” castmate Julia Jones (Leah Clearwater) tells OK!, “and, if he can, tries to beat him!”

3. Eclipse‘s “other name”
Security on Eclipse is so tight, the producers at Summit Entertainment hired off-duty SWAT-team members to guard the set and trailers. Some of the cops rearranged their vacations to work on the movie, boasting to fans that “the pay is three times better, and the work is 10 times easier,” a source tells OK!. And if you’re scouring Vancouver to find the set, here’s a hint: You know those location signs movie companies hang on telephone poles? Look for the ones that say, “Untitled Sports Movie.”

4. Kellan and Ashley are extremely close
They’re paired with other partners onscreen — he with Nikki Reed, and she with Jackson Rathbone — but Kellan Lutz and Ashley Greene are constant companions. “They live next to each other in the same Vancouver apartment complex,” an insider tells OK!. “They drive to locations together, eat lunch together and go to the gym together.” Is their spark more than platonic? Sources close to the pair insist they’re just best friends.

5. They play games — and Kellan’s got a kazoo!
Since Twilight filming began, Kellan and Ashley have rotated hosting trivia evenings for the cast, says co- star Peter Facinelli. They’ve even played the Twilight board game. “It’s mostly questions about the movies,” Peter tells OK!. “We get stuff wrong. It’s really sad. But it’s fun when we get together. Rob and Jackson will pull out their guitars, and Kellan will pull out his kazoo. I wish I had musical talent!”
